The earth’s atmospheric composition is experiencing a perturbation unprecedented in the recent history. Various human activities, including large-scale deforestation, fossil fuel harvesting and combustion, and industrial scale crop fertilization have tremendously upset the planet’s carbon and nitrogen cycles and led to large increases in the atmospheric abundance of greenhouse gases. These changes are ongoing and dynamic. Anthropogenic emissions of pollutants and greenhouse gases are undergoing rapid alterations in response to technological, economic, and regulatory pressures. Natural sources and sinks are dynamically responding to the warming environment, with unknown feedbacks. We employ a combination of ground, airborne, and space-based observations to investigate both natural and anthropogenic sources of these atmospheric constituents. We link observations with models probing scales that span from cities to the globe, quantifying and attributing emissions. This leads to improved understanding of carbon and nitrogen cycles which is crucial for future projections of climate and air quality, and is necessary to inform societal responses and mitigation efforts.
Science news article on conflicting reasoning behind recent rise in global methane includes discussion with Prof. Kort.
First paper from our Four Corners study is published in PNAS. This work demonstrates the use of airborne remote sensing to identify methane plumes at meter-level resolution in a complex environment. We also directly observe that emissions of methane from point sources in Four Corners exhibit a lognormal distribution, where the largest emitters contribute disproportionately to total basin emissions.
Paper led by graduate student John Ware is published in JGR-Atmosphere. Aerosol Lidar Observations of Atmospheric Mixing in Los Angeles: Climatology and Implications for Greenhouse Gas Observations.
Carbon dioxide measurements made by us and others on the ORCAS team show 400 ppm threshold making its way into the far reaches of the Southern Hemisphere, exceeding levels last seen millions of years ago when sea level and temperatures were higher than today.
We are excited that Research Assistant Emily Yang will be joining the PhD program this fall.
NASA Earth Observatory article on methane discusses our work in Four Corners and the TOPDOWN flights we led as part of that effort.
Successful conclusions to ORCAS! Excellent work by the whole team to manage flights in such a remote region of the world, and handle wind-evacuations with such grace. We are excited to look at the data in more detail (and sort photos from the field).
Paper on methane emissions from the Barnett shale bridging the gap between inventories and atmospheric studies is published in PNAS.
The 2nd post-launch OCO-2 Science Team Meeting was fun and productive- it is a very rich dataset!
We just completed a successful data workshop in Boulder that brought together multiple studies focused on emissions from oil and gas production. We are looking forward to seeing the finalized results that come out of these studies!
Welcome to Dr. Martin Hoecker-Martinez & Emily Yang, who have joined the group.
